Abstract

The purpose of this paper is to present a mathematical model for studying electromagnetic transients of a transformer connected in cascade with a synchronous motor. An exact equivalent circuit represents the system is developed using the distributed element analysis in the differentiating form. In addition, the model can be easily account for neutral point of the transformer which is connected to ground. In this study the load is represented in d ,g,o reference frame.
 Several methods for solving the mathematical model are used. The desired voltages and currents of this model can be easily computed. 
several cases are considered to explain the effects on system transients of different system parameters.
